Well made, well fitting shirt.
Size: Large, Color: Burgundy, Pocket Description: No Pocket
I love buying products that pleasantly surprise. This is a well made shirt made with quality fabric. I also like that it fit me perfectly, it's wrinkly resistant and great value for the money. I've brought this awhile ago and it's held up great in the wash. It's one of those causal wear shirts you can wear just about anywhere. Oh, and the part that pleasantly surprised me the most is the fit. It fit so well, people ask if I've been going to the gym or am working out (I haven't). Who knew all i needed was a nice fitting shirt?

Great quality- thick and soft t-shirt
Size: X-Large, Color: White, Pocket Description: Pocket
These are the softest, thickest long sleeved t-shirts ever. Highly recommend...cannot believe the price and that they are Amazon-basics...quality is that of a good popular brand name at three times the price. Bought one last week and washed it up and it's so nice that I bought several more. It is true to size- looks a bit on the big size until you wash it and then it's very true to size. Hubby is 6'1" (205lb) and wears an xl.

Yeah, they shrink, a lot.
Size: X-Large, Color: Light Grey Heather, Pocket Description: Pocket
I knew they would shrink but I needed to know if so on permanent press cycle. Well they shrink a lot. I bought two and they were very comfortable and soft. I'm not returning since Amazon made it clear they will shrink. I'm the dummy.

A Good Value
Size: X-Large, Color: White, Pocket Description: No Pocket
I really like these shirts and have ordered a number of them so far. They're warm and comfortable and are of overall good quality. They will shrink substantially, and the arm length will be reduced. That being said I just order them a size larger than what I typically wear and know that the sleeves will be a bit short. Otherwise they're a quality shirt. The material is thick, but not overly so, and they don't seem to fade even after numerous washes. These shirts are durable, well-made, and are a good value.

Great Quality, 100% cotton, buy 1 size larger. I’m 100% happy!
Size: Large, Color: Black Charcoal Heather Stripe, Pocket Description: Pocket
I will be buying more of these. I knew they were 100% cotton so I bought a large when I normally wear a medium. After I washed it in warm water and dried it in the dryer, it fits perfectly. The cotton is of great quality not thin and flimsy. I expect to get plenty of wear out of this t-shirt. Also, it did not fade. I recommend buying one size larger.
